8.Lifting: With forks unloaded,
verify correct lifting and
descent.
9.Travel: Pressing the death-
man, verify correct movement
forward and reverse.
10. Visual inspection of chains

LIFTER OPERATOR
USER’S KNOWLEDGE
WARNING
While using, this manual’s
instructions shall be observed,
as well as local/national legal
dispositions.
SAFETY CLOTHING
Each site’s observations should
also be observed while using the
lifter.
For example:
WARNING

national rules and obligations
is as must.
Clothes should be tight enough
to avoid traps. If necessary in
the working site, user should
also wear protective glasses,
helmet, gloves, and whatever
required.

2.10
MOVEMENT IN RAMPS
AND SPECIAL AREAS
WARNING
Using the lifter et-1000 for
transporting goods in ramps is
strictly forbidden.
Only permitted with the lifter
unloaded, if necessary.
WARNING
Do not turn in ramps.
Movement in ramps is delicate:
pay maximum attention and
care.
WARNING
Caution when moving on the
truck surface. Please make
sure that the truck is stopped.
The ramp used to place the
lifter onto the truck must be
resistant enough to bear the
lifter, taking into account the
vertical movement of the lifter.
Ramp should be firmly placed
on the ground in order to avoid
unexpected movements.
Pay maximum attention during
the loading and unloading of
the lifter on the truck.

2.11
MOVEMENT
Visibility
Do not drive forward when the
load does not permit complete
visibility. In that case, drive
backward, except when driving
into a service lift, where entering
backwards is forbidden.
If visibility difficulties remain,
another operator should indicate
the correct direction. In this case,
drive slowly and handle with care.
Verify that working area is
lightened enough.

2.12
TRANSPORT OF THE
LIFTER
WARNING
1.Unloaded, put forks in the
upper position.
2.Confirm that in and out
angles do not interfere with
the ground or transport
platform.
3.When using a wooden made
bridge between platform and
dock, make sure that the
planks can bear the lifter.
4.Use only the lifting hangers
to lift the lifter. (see picture)
6.Switch off and release
contact key.

2.13
TESTING
After transport or a long
warehousing period, functional
testing is necessary.
Three tests:
1.Daily inspection test. (See page
2.5), to be made by users.
2.Dynamic tests, to be made by
the technical service.
2.1.Movement test.
Confirm that the lifter moves
towards the correct forward-
reverse switch, and confirm
that the blocking brake works
properly.
With the lifter loaded, press
up and down buttons to make
sure of correct work.
2.2.Piling test.
Lift completely and descent
the load at maximum speed
several times.
2.3.Descending speed test.
Confirm that descending
speed is not more than 0.6
m/s.
3. Hold load test.
With the machine off, fully loaded
with the forks up, confirm that the
forks don’t move down at all, or
they move down but not faster
than 10mm/min.
